This document points out the differences the FM25L256B, FM25V02, and FM25W256 F-RAM devices. For most designs, the FM25V02 and FM25W256 devices can be considered equivalent or better than the FM25L256B. The three devices are identical in terms of pinout, package dimensions and composition, and read/write functionality. In terms of speed, both operate up to 20MHz but the FM25V02 allows read/write operations up to 40MHz. It also adds a sleep mode feature which effectively lowers the standby/idle current to 8μA.
